So today I clicked a twitter link because companies like to use it for official announcements, only to be greeted with a login page. Was annoyed then I remembered nitter exists. It just prompted me to install Privacy Redirect which I should have done ages ago.
I think we're reaching that point in the technology cycle where the money people have finally realized that running a social media platform is essentially unprofitable. People absolutely loathe ads and go to extremes to block them, and legislative and regulatory controls are starting to squeeze the manipulative aspects of social media such that what few ads the platforms can serve aren't as relevant anymore, and the data they collect from their users is protected in more and more jurisdictions.
So they're bailing on the open platform idea. They're slapping paywalls up, putting things behind required-accounts, and trying to build a walled garden they can control.
I wish them the best. I remember what happened to Prodigy, CompuServer, and AOL.
